Test Description

The numbers below refer to the step numbers in the diagnostic procedures.

• 2
  
  This step verifies that the malfunction is present.
• 3
  
  This step inspects for electromagnetic interference (EMI) on the CKP sensor circuits.
• 6
  
  Vertical lines across the face of the sensor could indicate foreign material passing between the CKP sensor and the reluctor wheel. Non-vertical lines across the face of the sensor may indicate a crack in the CKP sensor. Either of these conditions causes this DTC to set.
• 7
  
  Damage to the reluctor wheel would affect the CKP sensor output. To inspect the reluctor wheel, remove the starter and rotate the crankshaft while viewing the reluctor wheel through the CKP sensor hole. If you cannot determine if the reluctor wheel is damaged, the oil pan may have to be removed.
